IIRC, there was a ton of, let's call it, cause and effect going on in that "mishap."
First mistake was doing the job with other aircraft close by. No way to cordon off the area down wind.
Second, was not properly depuddling and purging the tank.
Third was using equipment that wasn't explosion proof.
It just got much, much worse from there.
I also remember a couple of guys dying on C-130s because they failed to follow the most basic safety procedures.
That shit didn't fly with me. I don't care how fast you want it fixed, we're not skipping crucial safety steps.
I never liked working in-tank maintenance when adjacent tanks had fuel in them.
Fortunately, you couldn't do that on the B-1B because of system design.
